Answer:
Phenols do not exhibit the same pka values as other alcohols;
They are generally more acidic.
Using the knowledge that hydrogen acidity is directly related to the stability of the anion formed, explain why phenol is more acidic than cyclohexane.
Explanation:
According to Bromsted=Lowry acid-base theory,
an acid is a substance that can release
ions when dissolved in water.
So, acid is a proton donor.
If the conjugate base of an acid is more stable then, that acid is a strong acid.
In the case of phenol,
the phenoxide ion formed is stabilized by resonance.

The resonance in phenoxide ion is shown below:
Whereas in the case of cyclohexanol resonance is not possible.
So, cyclohexanol is a weak acid compared to phenol.

Answer:
[C₆H₆] = 1.28 M
Explanation:
Let's determine the molar mass of benzene
Molar mass of benzene = 12g/m .6 + 6 . 1g/m = 78 g/m
Mol = mass / molar mass
9.99 g / 78 g/m = 0.128 mol
Molarity = mol/L
0.128 mol / 0.1 L = 1.28 M
CO3 = carbonate ion
So, CaCO3 = calcium carbonate
Other name for CaCO3 are: Limestone and Marble
